If you consider the example of Seshadri, you can see that both 17209/10 and 17235/36 do not violate the distance restriction when considered individually, and each rake of 17209 that participates in this RSA does not violate the distance restriction in a complete round trip between COA and NCJ. So, in this case, both the train as well as the rake restrictions are satisfied. In the Navjeevan RSA on the other hand, the rake does not violate the round-trip restriction, but individually, Navjeevan violates the restriction.
The incoming rake of Navjeevan at MAS would have completed a round-trip of 3500km (CBE-ADI-MAS or MAS-ADI-MAS whichever way you consider), and thus requires pitline attention.

Of course, this is more of just playing around with the rules, rather than anything meaningful, but considering that there are very few cases of such twisted RSA's (rules-wise), such cases will not stand up to detailed analysis. By and large, for the majority of trains, the guidelines are pretty straightforward (as I mentioned in
/blog/post/3087109 ) and can be implemented without any such confusion.
